Definitions

  • the present invention relates to improvements in double-bed knitting apparatus of the type comprising two needle beds inclined relatively to each other, and on each needle bed a set of holding-down sinkers staggered with respect to the needles by one linear pitch.
  • Such sinkers exert an elastic downward tension on the topmost thread of the fabric being knitted and thus allow of a weightless knitting operation.
  • Double-bed knitting apparatus comprising holding-down sinkers have been proposed before, per se.
  • Such an apparatus is described and shown, for example, in the German Patent No. 1,087,743 in which the sinkers are translatorily movable and also parallel to the axis of symmetry of the apparatus between an upper and a lower position.
  • These known machines had the disadvantages that the needles of one bed could not be arranged opposite to a sinker of the other bed, since the sinkers in their high-shift position protrude into the track of the respective needles. For this reason, such relative position of the two beds had to be chosen in which the needles are opposite each other, and
  • the task at the bottom of the present invention was the provision of a double-bed knitting apparatus comprising holding-down sinkers, in which each needle may take part in the knitting operation and which, therefore, allows the knitting of small-mesh fabrics and goods of normal knitting pattern.
  • the machine of the present invention is characterized in that the sinkers are pivoted to the frontrnost end of the knocking-over comb.
  • FIG. 1 is a section on the line II of FIG. 2 of the first example, vertically to the plane of symmetry;
  • FIG. 2 is a partial top plan view, the cam plate having been removed
  • FIG. 3 is a front view of the knocking-over comb with a needle and a sinker
  • FIG. 4 schematically shows the mode of operation of the sinkers
  • FIG. 5 is a section corresponding to the right-hand portion of FIG. 1, through the knocking-over comb of the needle bed of the second example.
  • the first embodiment shown in FIGS. 1 to 3, comprises two bedplates 2, 20 that are inclined to the plane of symmetry 1 and to which are secured the needle beds 4 and 4a respectively, by means of screws 3 and 3a respectively.
  • These bedplates are conventionally fixed in their mutual inclined positions, for example by a frame that is not shown.
  • the screws 3, 3a at the same time serve to fix the guide bars 5, 5a to the respective needle beds in each of which are longitudinally movable a number of parallel needles 12 and 12a respectively.
  • the outer web 8, 8a forms the upper abutment for the knocking-over comb 9, 9a of which the underside is urged against the front portion of the bedplate 2, 2a and is engaged in corresponding holes 11, 11a thereof through stop studs 10, 10a (of which only one is shown).
  • Each of the one-piece knocking-over combs 9, 9a (FIG. 3) comprises a supporting angle 13, 13a which holds together a number of riblike elements 14, 14a said number corresponding to the width of the needle beds.
  • Each of said elements comprises on its upper side two relatively thin blades 15, 15a; and between any two adjacent elements 14, 14a are pivotably mounted a sinker 16, 16a and an actuating means 17, 17a.
  • Each intermediate space between the two blades 15, 15a of each element 14, 14a forms the front end of the needle-guide.
  • All the sinkers 16, 16a appertaining to a needle bed are pivoted to the foremost end-portion of the blades 15, 15a on laterally protruding axle pins 18, 18a, while the actuating means 17, 17a in their turn are pivotably mounted on a common axle pin 19, 19a that passes through the blade rear ends.
  • a sinker 16, 16a and its appurtenant actuating means 17, 17a are arranged in each intermediate space between two riblike elements 14, 14a.
  • Each sinker and each actuating means comprises a toothed segment 29, 29a and 30, 300 respectively, which mesh so that a rotary movement of an actuating element is transmitted to the appurtenant sinker in the reverse sense.
  • the length of the blades 15, 15a and thus the spacing of the axles 18, 18a from the plane of symmetry 1 as well as the angle enclosed by the two needle beds 4, 4a is chosen such that the space swept by the sinkers in the pivotal movement thereof is situated within an angle enclosed by the plane defined by the undersides of the needles of the other needle bed and the plane of symmetry 1. Consequently the needle of the other bed opposite each sinker is freely movable along its entire path even when the sinker is in its upper position, i.e. raised from the fabric being knitted (as shown in FIG. 1 in dash-and-dot lines). The needles of said other bed thus may take part in the knit-ting operation to an unlimited extent.
  • each actuating means 17, 17a is firmly anchored a spring 27, 27a which through its free end 28, 28a is supported on one leg of the supporting angle 13, 1311.
  • This spring causes the respective actuating element 17, 17a to turn clockwise with respect to the needle bed shown on the right in FIG. 1 and, therefore, and by virtue of the transfer of motion through the toothed segments 29, 29a and 36, 30a, causes the appurtenant sinker 16, 16a to turn anticlockwise.
  • the latter thus engages by its nose 26, 26a a section of the fabric being knitted and bears down on the fabric with a force corresponding to the spring and pulls same downwardly.
  • each actuating means 17, 17a On the upper side of each actuating means 17, 17a is provided a control edge 31, 31a of which the end 32, 32a remote from the appurtenant sinker is angularly bent downwardly and is forwardly extended to a spring hook 33, 33a that is destined to engage, in a special mutual position of an actuating means and the appurtenant sinker, said sinker through a hump 34, 34a thereof and to hold the actuating means and sinker in this position.
  • Slotted pieces 35 to 37, 35a to 37a detachably secured to the cam plate 7, 7a are destined to coact with the control edge 31, 31a. All of these slotted pieces comprise angular free ends that have oblique control faces 38 to 40, 38a to 40a of which the dimensions are so chosen that upon movement of the cam unit or respectively, of the cam plate 7, 7a these faces one after the other hit the control edges 31, 31a of the individual actuating means 17, 17a and thereby trip the pivotal movement of the respective sinkers16, 16a.
  • the sinkers 16, 16a In various modes of knitting, such as in racked knitting, the sinkers 16, 16a have to be held in their high-swung position of rest during a certain length of time.
  • the slotted-pieces 36, 37 and 36a, 37a are connected to the cam plate, additionally to the slottedpiece 35 and 35a, one thereof (37, 37a) acting as stopping piece and the other (36, 36a) as tripping piece.
  • These pieces 36, 37 and 36a, 37a thereby are arranged in pairs towards the two ends of the cam plate, one stopping piece 37, 37a and a tripping piece 36, 36a together forming a pair of which the former is on the outside and the latter is on the inside.
  • the stopping piece 37, 37a in its arrangement corresponds substantially to the piece 35, 35a with the difference that the angled end thereof is somewhat longer so that this stopping piece turns the actuating means 17, 17a through a somewhat greater angle.
  • the dimensions are so chosen that by virtue of this greater pivotal movement of the actuating means the spring hooks 33, 33a become engaged over the humps 34, 34a of the respective slotted-piece and thereby hold the sinkers in the position of rest, against the action of the springs-27 as shown in the right-hand portion of FIG. 1 in dash-and-dot lines.
  • the tripping pieces 36, 3a that in each direction of movement of the cam unit are arranged behind the respective stopping pieces 37 and 37a, with their angled control faces 39, 39a only extend into the range of the rear angled portion 32, 32a of the control edge 31, 31a. Said control faces are so directed that the respective actuating means 17, 17a by the impingement of the respective control face against the control edge is lifted by a small amount which owing to the backlash or play of the mesh between the toothed segments 29, 30 and 29a, 30a
  • Each sinker 16, 16a comprises a lower beak '20, 20a which extends substantially along the circular arc of motion and to the upper end of which is joineda projecting nose 21, 21a that tapers downwardly to a tip.
  • each sinker on its end face of diiferent sides comprises two lateral projections staggered in height.
  • the lower of these projections 22, 22a (FIG. 4) is bounded on its underside by a slanted spreading edge 23, 230 while the lateral limit is formed by an edge 24, 24a that is parallel to the plane of the sinker.
  • the upper projection 25, 25a that protrudes over the other sinker side comprises on its underside a notch 26, 26a that represents the catch.
  • FIG. 4 is schematically shown the mode of operation of the sinker when the needle beds have been swung into a plane, and in which behind each sinker is shown a front elevation thereof.
  • the catch thereof engages on its other side the respective yarn section which by the spreading edge of that sinker of the counterbed which extends on the side of the opposite needle corresponding to this yarn section, has been moved to a position which ensures a safe engagement of the yarn by the catch.
  • the constructive assembly of the embodiment according to FIG. 5 corresponds in a far-reaching extent to that of the first embodiment, so that the illustration thereof may be limited to only one of the two needle beds.
  • a knocking-over comb 43 to which are pivoted on one hand a plurality of sinkers 44 on the axle pin 45 and, on the other hand, appurtenant actuating elements 46 on the axle pin 47, the swing or angular movement of the actuating element 46 being transmitted to sinker 44 through two toothed segments 48 and 49.
  • the only substantial difference between these two embodiments is the arrangement and mode of operation of the spring 50 that acts on the actuating element and in the second embodiment is formed as snap spring.
  • each comprises a stopping piece and a releasing piece, the former being arranged outside and the latter inside.
  • Each stopping slotted-piece imparts to the actuating means a pivotal movement or swing beyond the deadcenter position of the snap spring, which swing is limited by the impingement of the edge 60 of the actuating means against the surface 57 of the bedplate.
  • the releasing slotted-pieces impart only a relatively slight rearward swing to each actuating means, which suffices to turn back again the snap spring 50 beyond the deadcenter position so that said spring again may restore the respective actuating means and the associated sinker to the working position.
  • the spring hook (33, 33a) of the actuating means according to the first embodiment, which hook coacts with the hump (34, 34a) of the sinker.
  • the apparatus shown in FIG. 5 operates in exactly the same manner as the apparatus ac cording to the first example, in particular with respect to the space swept by the sinker during the swing thereof, as well as to the configuration and action of the lateral sinker extensions.
  • a double-bed knitting apparatus comprising two symmetrical needle beds inclined towards each other and each including a knocking-over comb, a set of holdingdown sinkers on each needle bed, said sinkers being staggered with respect to the needles, and two cams, each of which reciprocates parallel to the plane of symmetry and parallel and adjacent to one needle bed, wherein the improvement comprises a pivotal mounting for each sinker on the end of one of said combs adjacent to the plane of symmetry, said mounting being so located that the sinker can pivot close to the plane of symmetry and close to the plane of the undersides of the needles of the opposite needle bed, and an intermediate pivoted driving member for each sinker, having a driving engagement with the sinker and having a control edge extending into the path of movement of one of said cams.
  • a double-bed knitting apparatus comprising a catch projecting from one side and a spreading edge projecting from the other side of each sinker.
  • each intermediate pivoted member is spring loaded to drive its sinker toward the working position, and is engageable with a latch for holding its sinker away from the Working position.
